7 '0 all whom it may concern:

Be it known that I, JOHN H.'CocsWnLL, a citizen of the United States,residin at Lansing, in the county of Ingham'and tate of Michigan, haveinvented certain new and useful Improvements in Atomizers forInternal-Combustion Engines, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to new and useful improvements in automaticatomizers for internal combustion engines and the object in view is toproduce a simple andefiicient. device of this nature which may be easilyand quickly attached to the manlfold' of an engine and adapted to admitair, proportionate to the quantity of fuel passing through the manifoldto the engine.

' The present invention consists of a simple.

device of this nature which will be automatic in its action and serve tothoroughly mix the gas and air before entering the combustion cylinder,thus economizing in fuel and servin to reduce to a mlnlmum the depositof car on on the inner surface of the cylinder.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a sectional view showing the same as applied to a manifold.

Fig. 2 IS an enlarged central sectional view through the device.

Fig. 3 is a sectional view on line 33 of I Fig.

Fig. 4 is an end view of the atomizer, and Fig. 5 is a detailedsectional view of a modification of my invention.

Reference now being had to the details of the drawingsby letter, Adesignates the shell of the atomizer having a circumferential, angularshoulder B near one end for a. wrench hold and the one end of the shellis circumferentially threaded as at C and adapted to engage the threadsD formed in the marginal edge of the opening in the manifold E. Saidshell, which is cylindrical shaped, has circumferential threads F at oneend and H is an interiorly threaded cap fitted over said circumferentialthreads of the shell and the end of the cap has its inner sur-' faceconically shaped and tapering to a point, and K designate ducts throughwhich the air is allowed to enter'tho shell. A valve N, of cylindricalform,

is mounted within the shell and has a conically shaped end 0, conformingto the taper on the inner face of the cap and the conical portion of thevalve 1s adapted to form a art to regulate thepassage of air through t educts K. Said valve 1s longitudinally channeled as at L, and R is acoiled spring which is mounted within the shell bearin against thebottom of the latter about t e inner threaded end and the outer end ofsaid springs bear against the valve N and normally holds the sameagainst the cap in the manner shown. The purpose of said spring is tonormally hold the outer end of the valve 'in closed relation with theduct K and the tension of said spring may be adjusted by the positionthe cap assumes upon the threaded portion of the shell. For instance, ifit is desired to increase the tension of the spring, causing a greatersuction to be required to actuate the valve to permit air to enter, thmanifold than would otherwise be the case, the unscrewing of the captending to lessen the tension of the sprin In operation, the device isapplied'to the manifold or to the carbureter and the bore of thecylinder and, when the engine is in operation, the suction upon themanifold as 1t overcomes the tension of the spring will cause the valveto unseat and draw in air in suflicient quantity to thoroughly atomizethe fuel with 'which it entering the comton and serve as a means foreconomizing in fuel. a What I claim to be new is An atomizer forinternal combustion en'- comprising a shell adapted to be attached tothe manifold of an engine, and having a chambered portion, the innerpor-' tion of which is contracted, saidchamber having an annularshoulder, a hollow cylindrical valve with its outer end' conical shapedand provided with apertures therein an adjustable cap interiorlythreaded and gines,

the pipe or opening between duct T leading through the a minimum thedeagainst sei sheulcler and the inner endl or" g I f I i eer vev thevalve, endl a jam nut upon the threedledl circumference of the shell. 10
